To which jQuery 1.5 changelog do you refer? There is not an official jQuery 1.5 changelog yet, because there is no jQuery 1.5 yet. If you're referring to the changelog in the recent community updates post, that is just a log of changes that have happened thus far, it is not a complete changelog.

When the bug is fixed, this ticket will be closed. It is certainly something we are planning to address for 1.5 - otherwise we'll be getting dupes on this issue until the end of time. :)
